Question

25 Points!! What is the volume of the prism 1 1/2ft 3 1/2ft 2 1/2 ft? Please answer when you have the time to.

Answer 1

Answer:

The first one: 13.125 ft³

The second one: 67.5 ft³

Step-by-step explanation:

For the first one:

The volume of a prism is length x width x height.

So, in this shape, the length is 3 1/2, the width is 2 1/2, and the height is 1 1/2.

However, you can conver 1/2 to .5, to make it easier to multiply.

So, 3.5 x 2.5 x 1.5 = 13.125

Make sure to add ft³, the ft is the unit, feet, and the ³ is used to denote volume, because volume is 3  dimensional.

For the second one, same formula:

Length = 6, width = 2 1/2, and height = 4 1/2

6 x 2.5 x 4.5 = 67.5

Again, make sure to add ft³, the ft is the unit, feet, and the ³ is used to denote volume, because volume is 3 dimensional.

Answer 2

Answer:

13.125 $ft^{3}$

Step-by-step explanation:

Volume is base * length * height.

In this case, the dimensions are 1.5, 3.5, and 2.5.

Assuming these values are the base, length, and height,

1.5 * 3.5 * 2.5 = 13.125 $ft^{3}$.

Also, using the volume formula, the bottom shape's volume is 67.5 $ft^{3}$.

Hope this helps!
